To all whom it may concern:

. Be it known that I, SIDNEY D. KING, of

Pittstou, in the county of Luzerne and State of Pennsylvania, haveinvented certain new and useful Improvements in Car-Trucks; and

I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art towhich it appertains tomake and use the to same.

'Myinvention relates ear-trucks. g

Hitherto it-has been customary to provide the bcarihg-bcar'n. of acar-truck witha pair :5 of trusses, one on either side, sccurel ast-'ened near the ends-of theupper side and struug'overa small dependingsaddle midway between theeuds. Thissaddlc has generally been(miistructrd of such thickness or depth that it would notinterferewith'the free action of the'spring by striking against the lowerparallelsupport on which the springs are located.

The object of my presentinvention is to 'furthc'r stretgthen' the uppersupport by bringing the trusses to a more nearly vertical.

position. I

With this end in view myinvention con sists in a truss-saddle secured tothe bearingbeam and'ada ited to span the parallel supporting-beard; Ideath it. v

My invention further consists in certain features of construction andcombinations of parts, as Willi]!!! hereinafter fidIydescribed, andpointcdfout intb'e clainis.
